My Acer A200 Tablet will not stay connected

[Angie Mauldin]

I hope I can make sense here. I connect my tablet to my mobile hotspot on my phone. It stays connected for maybe 2 minutes then it just stops. It still says it's connected but I can't get into the web or google play store. I've reset it and cleared out all cookies and data. Please help. It just started doing this today.
